SKATE SHARPENER.

Application filed March 6, 1926. Serial No. 92,812.

This invention relates to improvements in sharpeners, particularly applicable upon the runners of ice skates and which contemplates the provision of companion interlocking discs having an emery wheel mounted between their inner sides and of relatively smaller diameter than the discs whereby the edge of a skate runner may be received between the inner sides of the discs for abrasion against the periphery of the emery wheel whereby the skate may be sharpened when traversed between the disks.

Another object of. the invention resides in the provision of spaced parallel relatively narrow slotted portions provided in the discs for the reception of relatively narrow skate runners whereby the invention may be equally and effectually applied to skate runners of various widths.

lVith the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claim.

In the drawing Figure 1 is a fragmentary elevation of a skate with the invention applied thereto.

Figure 2 is an end elevation of the invention while in use.

Figure 3 is a vertical sectional view taken through the invention when receiving the edge of a skate within the slotted portions of the discs,

Figure 4 a perspective of the elements forming my invention.

Figure 5 is an elevation of the invention with a disc removed and applied to a skate runner.

Referring to the drawing in detail, wherein like characters of reference denote corresponding parts, the reference character indicates companion discs preferably formed of non-rust material such as aluminum; each of which having spaced parallel inwardly extending fingers 11 and correspondingly extending innerfitting lug members 12 upon diametrically opposite sides thereof and adapted for interfitting and interlocking engagement as clearly illustrated in Figure 2 of the drawing. An emery wheel such as indicated at 13 being of the same configuration but of smaller dimensions in contradistinction to the discs 10 providing a relatively large opening 14 centrally thereof for the reception of a bushing 15 preferably formed of lead or bronze and having slotted port1ons 16 provided within the opposite sides thereof for locking the outwardly extending keys 17 provided upon the opposite sides of an interiorly threaded bearing sleeve 18 and mounted upon a bolt 19 extending through aligned openings 20 provided in the discs 10 and having its outer free end fitted with a knurled nut 21 whereby the said emery wheel 13 will be centered and held against accidental displacement and retrograde movement between the respective in ner sides of the discs 10 after the latter have been arranged in the interlocking position as clearly illustrated in Figure 2 of the drawing.

It is apparent that the runners 22 of a skate, not shown, may be received between the inner sides of the discs 10 and the knurled nut 21 screwed home upon the bolt 19 and having its edge exposed and arranged in contacting engagement with the peripheral edge of the emery wheel 13 whereby the sharpener or the invention, as completed, may be traversed longitudinally of the skate runner 22 to facilitate the sharpening thereof.

In order that the invention may be applied equally and effectually as for the sharpening of skates, having relatively narrow edges such as indicated at 23 at the lower sides of the discs are provided relatively flat portions 24 intersected by vertically disposed and aligned slots 25 provided for the reception of such edges 23.

It will thus be noted from the foregoing description and accompanying drawing that the invention may be utilized as a sharpener upon the various sizes and widths of skate runners and yet owing to the construction thereof may be readily and easily and conveniently carried within the pocket and take up no more space than the ordinary size watch,

The invention is susceptible of various changes in its form, proportions and minor details of construction, and the right is herein reserved to make such changes as properly fall within the scope of the appended claim.

Having thus described the invention, what is claimed is A sharpener for use upon ice skates comprising a pair of companion discs, each of which having spaced paralled inwardly extending fingers and correspondingly disposed lugs provided upon diametrically Q rezzeve opposite sides thereof for interlocking engageinent one with the other, a relatively small einery wheel fitting a bushing eontrally thereof, an interlorly threaded sleeve providingkeys upon diiunetrically opposite sldes thereof and fitted Within the con-e spending sides of the bushing} and a bolt ex; tending transversely and centrally through the discs and sleeve and u knurled out upon its opposite end whereby guided by the runners and edge of a skate may he positioned and held between the discs for abrasive action against the emery Wheel.

In testimony whereof I afiix my signature.

STEVE TURI.
